Updated M34 with T5i on Fixed Tripod

Here is another go at M34, the open cluster in Perseus, this time with my new T5i camera. Compared to the previous attempt with the Rebel XT, there is a noticeable difference in the number of visible stars and the clarity.

M34 of fixed tripod
Canon T5i - December 27, 2013: Stack of 37 subs, 12 bias at 300mm, f/5.6, ISO 3200, 1.3 sec
M34 of fixed tripod
Canon Rebel XT - November 12, 2013: Stack of 41 subs, 25 darks, 20 bias; 300mm, f/5.6, 1.3 sec, ISO 1600
My new image is flipped (upside down) because it was taken in the setting sky (West) rather than the rising sky (East) earlier in the Fall. With around the same number of light frames, the T5i at ISO 3200 clearly picks up more stars! Can't wait to try it out with my EQ mount rather than a fixed tripod.
